1 PS: Talker identifier
2 IMP: Datagram identifier
3 D1: Sentence specifier
4 tt: Time
5 dd: Date
6 M: Type of measurement
•  D = Depth
•  T = Temperature
•  C = Catch
•  B = Bottom
•  N = No sensor
•  M = Marker
7 U: Unit of measurement (Always SI units)
•  M = Depth measurements (metres)
•  C = Temperature measurements (Celsius)
8 SNo: Sensor number
9 MNo: Measurement number
10 C: Channel (This is the number of the communication channel for the current data source. (1 ‑ 30))
11 V: Value (This is the magnitude of the measurement made by the sensor.)
12 Cr: Change rate
13 Q: Quality
•  0 = There is no connection between the sensor and the receiver.
•  1 = One or two telemetry pulses are lost. The measured value is predicted.
•  2 = The measured data is reliable.
14 In: Interference
•  0 = Interference is not detected.
•  1 = Interference is detected.
15 SL: Signal level (dB // 1 µPa)
16 NL: Noise level (dB // 1 µPa)
17 G: Gain (0, 20 or 40 dB)
18 Cb: Cable quality
•  0 = The cable is not connected.
•  1 = The cable is in good working order.
•  2 = The cable is short-circuited, or the hydrophone current is too large.
19 error: Error (0 means that no errors ares detected. Any other value indicates an error condition.)
20 chksum: Checksum (The checksum field consists of a "*" and two hex digits representing the exclusive OR of all characters between, but not including, the "$" and "*" characters.)
